Description

Technical Field

[0001] The invention relates to the technical field of anti-pinch subway doors, in particular to a safe anti-pinch subway door. Background Art

[0002] In the modern urban transportation system, the subway has become an important public transportation tool due to its advantages such as high efficiency, punctuality and large capacity. As an important passage for passengers to get on and off the train, the safety of subway doors is directly related to the safety of passengers' lives and property. The design of traditional subway doors mainly considers the door's opening and closing speed, durability and coordination with the vehicle. However, with the increase in subway operating speed and passenger flow, traditional subway doors have exposed some problems in terms of safety, especially in the anti-pinch protection function.

[0003] When traditional subway doors encounter obstacles, they may cause passengers or objects to be pinched due to the lack of effective detection and response mechanisms. In this case, the closing action of the door will not automatically stop or reverse, which increases the probability of accidents. In addition, due to the complex operating environment of the subway, traditional anti-pinch technology is often difficult to adapt to various complex situations, such as obstacles of different sizes and shapes, and accurate detection under different environmental conditions, and cannot achieve efficient predictive anti-pinch.

[0004] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a safe anti-pinch subway door. Summary of the invention

[0005] The object of the present invention is to provide a safe anti-pinch subway door to solve the common problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a safe anti-pinch subway door, comprising a door frame, a control drive box is installed on the top of the door frame, an opening and closing mechanism is arranged in the control drive box, the opening and closing mechanism comprises a guide bar installed in the box, a base is installed on the guide bar, a servo motor is arranged on the base, a main gear is connected to the output end of the servo motor, a rotating gear is meshed and connected to the adjacent sides of the main gear, a connecting shaft is installed in the shaft hole of the rotating gear, a connecting shaft end is rotatably connected to a connecting rod, both ends of the connecting rod are rotatably connected to linkage arms, a rotating seat is arranged at the rear ends of the two linkage arms, and a left push block and a right push block are rotatably connected to the two rotating seats respectively, a door panel seat is installed at the bottom of the left push block and the right push block, and a left door panel and a right door panel are respectively installed on the two door panel seats.

[0007] As a preferred technical solution, a guide slot is provided on the guide bar, and multiple groups of left push blocks and right push blocks are provided, and the multiple groups of left push blocks and right push blocks are slidably connected to the guide slot.

[0008] As a preferred technical solution, an anti-pinch component is arranged between the left door panel and the right door panel, and the anti-pinch component includes an anti-pinch rubber strip installed on the outer wall of the door panel, and a cavity is arranged inside the anti-pinch rubber strip, and a plurality of groups of rubber columns are arranged in the cavity at equal intervals along the vertical direction.

[0009] As a preferred technical solution, a controller is installed in the control drive box, infrared detector 2 is installed at the center position of the control drive box, infrared detector 1 is installed on both sides of infrared detector 2, and a pressure sensor is installed on the inner wall of the cavity between adjacent rubber columns. The controller is connected to infrared detector 1, infrared detector 2 and the rubber column.

[0010] As a preferred technical solution, the controller is connected to the servo motor to control the start and stop of the servo motor, the infrared detector 1 and the infrared detector 2 are used to detect the distance between obstacles in front of the door panel, and the pressure sensor is used to monitor the pressure changes of the anti-pinch rubber strip in real time.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention is a safe anti-pinch subway door. By means of an infrared detector and a pressure sensor, the obstacle in front of the door panel and the contact pressure between the door panel and the obstacle can be monitored in real time, so that when an obstacle is detected, the closing action of the door can be stopped in time or the door can be reversed to open, thereby effectively preventing passengers or objects from being pinched and significantly improving the safety of passengers getting on and off the train.

[0014] Through the precise control of the servo motor, the opening and closing of the door is smoother and faster. At the same time, when an obstacle is detected, the door can respond quickly, avoiding the long-term clamping or jamming that may be caused by traditional subway doors, and improving the efficiency of the use of subway doors.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0026] Example

[0027] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention provides a technical solution for a safe anti-pinch subway door: Figure 1As shown, the safety anti-pinch subway door includes a door frame 1, and a control drive box 2 is installed on the top of the door frame. An opening and closing mechanism is arranged in the control drive box 2, and the opening and closing mechanism includes a guide bar 3 installed in the box. A base 31 is installed on the guide bar 3, and a servo motor 32 is arranged on the base 31. The output end of the servo motor 32 is connected to a main gear 33, and the adjacent side of the main gear 33 is meshed and connected to a rotating gear 34. A connecting shaft 35 is installed in the shaft hole of the rotating gear 34, and a connecting rod 36 is rotatably connected to the end of the connecting shaft 35. The two ends of the connecting rod 36 are rotatably connected to linkage arms 37, and the tail ends of the two linkage arms 37 are provided with rotating seats 38, and the two rotating seats 38 are respectively rotatably connected to the left push block 40 and the right push block 39. A door panel seat 41 is installed at the bottom of the left push block 40 and the right push block 39, and the two door panel seats 41 are respectively installed with a left door panel 42 and a right door panel 43.

[0028] The guide bar 3 is provided with a guide slot 301, and the left push block 40 and the right push block 39 are provided with multiple groups, and the multiple groups of left push blocks 40 and the right push blocks 39 are slidably connected with the guide slot 301.

[0029] like Figure 2 As shown, an anti-pinch component is arranged between the left door panel 42 and the right door panel 43, and the anti-pinch component includes an anti-pinch rubber strip 44 installed on the outer wall of the door panel. A cavity 441 is arranged inside the anti-pinch rubber strip 44, and multiple groups of rubber columns 45 are arranged in the cavity 441 at equal intervals along the vertical direction.

[0030] like Figure 3 As shown, a controller 54 is installed in the control driving box 2, an infrared detector 2 52 is installed at the center of the control driving box 2, infrared detectors 1 51 are installed on both sides of the infrared detector 2 52, and a pressure sensor 53 is installed on the inner wall of the cavity between adjacent rubber columns. The controller 54 is connected to the infrared detector 1 51, the infrared detector 2 52 and the rubber column 45.

[0031] like Figure 4 As shown, the controller 54 is connected to the servo motor 32 to control the start and stop of the servo motor 32. The infrared detector 1 51 and the infrared detector 2 52 are used to detect the distance between obstacles in front of the door panel, and the pressure sensor 53 is used to monitor the pressure change of the anti-pinch rubber strip 44 in real time.

[0032] Through the above embodiments, the safety anti-pinch subway door of the present invention can effectively improve the safety of passengers getting on and off the train, while ensuring the efficient operation and reliability of the subway door.

[0033] In this embodiment, the opening and closing of the subway door is precisely controlled by the servo motor 32, ensuring the smooth movement of the door panels 42 and 43. When the door panel encounters an obstacle during the closing process, the infrared detector 1 51 and the infrared detector 2 52 will quickly detect the obstacle and transmit the signal to the controller 54. The controller 54 then instructs the servo motor 32 to stop running or reverse the running direction, thereby preventing the door panel from clamping the obstacle. In addition, the pressure sensor 53 can monitor the pressure change of the anti-pinch rubber strip 44 in real time, further ensuring the accuracy of the anti-pinch function.

[0034] In order to further improve the reliability of the anti-pinch function, the present invention also uses multiple groups of rubber columns 45, which are evenly distributed in the cavity 441 of the anti-pinch rubber strip 44. These rubber columns 45 can adapt to obstacles of different sizes and shapes, ensuring that the existence of obstacles can be accurately detected under various environmental conditions. When the door panel encounters an obstacle, the rubber column 45 will be subjected to pressure, and the pressure sensor 53 can detect this pressure change and transmit the signal to the controller 54, thereby achieving a quick response.

[0035] The anti-pinch component design of the present invention not only improves the safety of passengers getting on and off the train, but also realizes the synchronous opening and closing of the door panels by optimizing the design of the opening and closing mechanism. The linkage action of the connecting rod 36 and the linkage arm 37 enables the door panels 42 and 43 to move synchronously, and the structure is simple and easy to maintain. This design not only reduces the failure rate of subway doors, but also reduces maintenance costs and improves the use efficiency of subway doors.
